摘要

本研究之目的旨在探討以台灣相思樹木材及栽培香菇後之太空包廢料為原料，經篩選適當尺寸(40/60 mesh)後，置不銹鋼金屬模具上，以冷壓機加壓成型，研製尺寸85 mm(L)×35 mm(W)×25 mm(H)之絕乾比重1.0固態木磚。次經炭化後製造固態木炭磚，分析炭化處理前後熱值等相關性質，並探討其固態木炭磚對台灣相思樹木材及其木炭磚熱值之效應。太空包廢料之全纖維素較之台灣相思樹木材者低，而其灰分值及1% NaOH抽出物含量較高。太空包廢料及台灣相思樹木材均隨炭化溫度增加，其炭收率呈下降趨勢。太空包廢料固態木炭磚灰分比台灣相思樹木材及未炭化太空包廢料者高。台灣相思樹木材熱值為25670.4 kJ/kg，太空包廢料之熱值為24269.2 kJ/kg，較之前者低1401.2 kJ/kg（減少5.5%）。固態木炭磚熱值隨炭化溫度增加(250~450℃)而增加趨勢。太空包廢料與台灣相思樹木材炭化後比未炭化試材，其熱值分別增加5.8~11.2%及5.8~15.6%。且兩者之炭化溫度(T)與試材熱值(HV)呈一次直線回歸極顯著相關。又兩者之可燃物含量，均隨炭化溫度增加而降低。綜合評估，太空包廢料回收製造生質燃料可行性極高，如經炭化處理更可提升其熱值。

The purpose of this research is to investigate the development of oven-dried density 1.0 g/cm^3 of solid wood briquette (SWB) by using fresh Taiwan acacia (TA) and the waste cultivation bag (WCB) as a raw material. The method was to screen the suitable size (40/60 mesh), and then to fill them in the stainless steel mould and with the cold press machine compression formation. The products size was set at 85mm(L)×35mm(W)×25mm(H). After charcoalization, the heat value and the other related properties (including charcoalized yield, pH…) of solid wood charcoal briquette (SWCB) were analyzed, and the efficiency of heat value compared the solid wood charcoal briquette with fresh Taiwan acacia and its wood charcoal briquette were also estimated. Holocellulose showed that the WCB is less than the TA, but ash and 1% NaOH extractives were reversed. The charcoal yield increased with increasing charcoalization temperature for both WCB and TA. Heat value of TA is 25670 kJ/kg and WCB is 24269 kJ/kg. The WCB is about 1401 kJ/kg less than TA (a reduction of 5.5%). Heat value also increases with increasing charcoalization temperature (250~450℃) for solid wood charcoal briquettes. Compared with after and before charcoalization, the WCB heat value increases 5.8~11.2%, and fresh TA increases 5.8~15.6%. There existed linear regression relationship between charcoalization temperature (T) and heat value (HV) and the correlation is highly significant (0.01 level) for WCB and fresh TA. The test results showed that the high feasibility of the manufacture of biomass energy for WCB and then treated with charcoalization in producing solid wood charcoalized briquettes, would enhance its heat value.
